OIL-DISPENSING APPARATUS.

Specification of Letters Patent.

Patented Aug. ME, 19 1?.

Application filed. November 26, 1915. Serial No. 63,577.

To all whom it may concern:

Be it known that we, HOMER H. DANIELS and NnLm NAFUS, citizens of the United States, residing at Oswego, in the county of Labette and State of Kansas, have invented certain new and useful Improvements in Oil- Dispensing Apparatus, of which the following is a specification.

Our present invention has relation to a new and improved dispensing apparatus that is especially designed to be used in handlingheavy machine oils in garages, etc. the main objects thereof being to provide for the accurate measuring of the oil prior to its dispensement and to afford facilities for discharging the same under pressure subsequent to the measuring operation.

Another object of the invention is to provide a device of this character which occupies the minimum amount of floor space, consistent with its satisfactory operation.

Another object is to provide a device of this character whereby the mechanism thereof and the oil dispensed thereby is effectually protected from dust and other foreign matter.

, A further object of our invention is to provide a device of the type in question that is extremely simple in construction, strong and durable, and highly practical both from the standpoint of the manufacturer and the standpoint of the user; and which, it is be lieved, may be manufactured at a comparatively low cost.

Various other objects and advantages will become apparent during the continuance of the following description.

These objects are accomplished by such means as are shown in their preferred form in the accompanying drawings, described. in the following specification and then more specifically pointed out in the appended claims.

In the accompanying drawings wherein like characters designate like parts throughout the several views:

Figure 1 is a view in side elevation showing my invention as in its preferred embodiment; the storage tank being shown buried in the ground while the dispensing apparatus is mounted in the usual manner.

Fig. 2 is a view in vertical section illustrating in detail the supporting stand and the dispensing apparatus. 7

Fig. 3 is a fragmentary view of the dispensing apparatus.

In reducing our invention to practice, we provide a suitable stand 10 that is preferably constructed of metal and provided with a hinged door 11 whereby access may be had to its interior and whereby dust and grit are excluded from the oil-receiving ves-- sels 31 and 33. At its upper end, the stand 10 is constructed so as to be capable of re ceiving a compression cylinder 12, the latter being provided with an annular supporting flange 13 to rest upon the enlarged portion 14 of the stand, as clearly shown in Fig. 2. A weighted plunger 15 is arranged to operate within the cylinder or dispensing chamber 12 and is preferably constructed in a manner whereby it will form a comparatively fluid-tight connection with the interior side wall thereof, and at'the same time provide for the dischargement of the contents of the cylinder under pressure, such as will be subsequently pointed out. Although as above stated the walls of the plunger form a comparatively fluid-tight connection with theinner periphery of the cylinder it is deemed expedient to employ a packing ring 16, that may be arranged in the manner shown so as to further assure the fluid-tight connection.

A series of standards 17 extend through the supporting flange 18 of the cylinder and the adjacent projecting flange of the packing ring so as to adequately support a plate 18 in spaced relation to the upper end of the cylinder. Any suitable means may be em ployed to retain the plate in position on the standards; however in the drawings we have shown a plurality of nuts 19 for accomplishing this purpose. This plate is designed to support a registering indicator such as indicated by the numeral 20 that carries a depending actuating rod 21 to be raised by the plunger 15 during its upward movement. Consequently it will be recognized that the quantity of fluid in the cylinder may be readily ascertained by referring to the indicator 20; the latter of course registering in consistence with the height of the plunger 15 with respect to the cylinder.

In order to exclude foreign material from the working parts of the apparatus and at the same time to permit the numerals of the indicator 20 to be readily viewed by the operator, a globe 22 may be arranged thereover and supported by the annular ledge 23 of the supporting flange 13. The globe is of course preferably constructed of glass.

At its lower end the cylinder 12 has con-- nection with a three-way valve comprising a. valve casing 24, the latter accommodating a valve member 25 that is designed to establish communication between certain of the passage ways 26, 27 and 28, at different times so as to provide for the proper dispensement of the material being handled. An operating handle such as indicated by the nu meral 29 may be associated with the valve in the manner shown in order to facilitate the proper actuation thereof.

Within the body 10 at a point appreciably below the door opening we arrange a suitable bracket 30 for supporting a drip pan 21 while a bracket 32 may be arranged immediately adjacent the opening so as to support a container such as indicated by the numeral 33 that is to receive the fluid from the cylinder. It will be appreciated that the material overflowing the container 33 will fall into the drip pan 31 where it may be collected and returned to the storage tank.

The storage tank 34: is preferably sunk into the ground in the usual manner and provided with an upstanding pipe 35 through which it may be refilled. It is of course desirable to provide a cap 36 to normally close the upper end of the pipe 35 and thus exclude foreign matter from settling into the tank. The tank 34 may be also connected with a compressed air line, such as indicated by the numerals 37 and 38 whereby air may be introduced into the same for forcing the oil through the outlet pipe such as will be presently described. A controlling valve 39 is of course associated with the air line 38 so as to regulate the supply of air entering the tank, while an indicator 40 may also be employed so that the air pressure may be readily ascertained. Furthermore a safety valve 41 may also be arranged in connection with the air line so as to relieve the pressure in the tank and thus guard against the straining and consequent bursting thereof.

The tank is further provided with an outlet pipe 42 whose inner end terminates at a point only appreciably above the bottom thereof, while its other end has connection with another pipe 13, exteriorly of the tank, such as shown at 44, while this latter pipe is in turn connected with the passage way 27 of the valve casing 2% by a pipe -15, as at L6. Consequently it will be seen that the contents of the storage tank may be forced through the pipes 42, 43 and 45 respectively directly into the cylinder 12 by way of the valve 25.

In the operation of our invention the air is of course introduced into the storage tank. However when this occurs the valve 25 may be moved to the position such as shown in Fig. 3 to prevent the entrance of the oil, or other material into the cylinder 12. Conselatter will actuate the indicator 20. The operat'or, by referring to the indicator may as certain when the desired amount of material has entered the cylinder whereupon the controlling valve may be'again shifted to assume the position shown in Fig. 3 to close the aassa e wa 27 and to establish com munication between the passage ways 26 and 28 respectively. As soon as the pressure 1 upon the material in the cylinder is relieved, the plunger 15 will of course have a tendency to return by gravity to its initial position thereby discharging the material un der force through the respective passage ways and hence to the container 33. The weight of the plunger 15 may be varied according to the consistency of the'fluid that is being handled 2'. 6. increased when handling very thick oils, such for instance as heavy machine oil orthe like, and decreased when handling material of a lesser consistency. The pressure exerted on the material that is in the cylinder greatly expedites the dis pensement thereof in that it eliminates the slow flowing of the material such as would otherwise occur in the event that a material of heavy consistency was being handled.

F roin the foregoing it ,is believed that the advantages and novel features of our invention will be readily understood and therefore further detailed description is deemed unnecessary. y

In reducing our invention to practice we find that the form referred to herein as the most practical and preferred embodiment is the most efficient but realizing that certain conditions will necessarily vary in concurrence with the adoption of our de vice, we desire to emphasize the fact that various minor changes in the. details of construction and in the proportion of parts may be resorted to when required without sacrificing any of the advantagesof our 7 invention as defined in the appended claims.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is: r
